1. In-Season Nitrogen Management for Sub-Surface Drip Irrigated CornIrrigation water and nitrogen @I) management for subsurface drip irrigated (SDI) corn was evaluated from 2004 through 2006 at the South Central Agricultural Laboratory of the University of Nebraska. SDI irrigation and N management strategies to increase both water and N use efficiency were compared to preplant N application for hrrow irrigation, commonly used in the area. Irrigation water levels of 100, 75 and 50% of measured evapotranspiration (ET) were applied with SDI, and N was applied in treatments... |
2. Evaluation of Nitrate Leaching Potential from Slow and Controlled Release Nitrogen Fertilizer Application to Irrigated CornThe use of slow and controlled release nitrogen (N) fertilizers as a practice to reduce nitrate leaching from irrigated corn was evaluated on coar se-textured soils in the Central Platte River Valley of Nebraska in 2007 & 2008. Slow-releas e methylene urea (MU) and polymer-coated urea (PCU) were compared to a standard fertil izer of urea ammonium nitrate (UAN) solution. Flooding in 2007 severely impacted the study site, and results are not reported here. Saturated soils were common at the site in... |
3. Use of Biostimulants for Increased Nutrient Uptake in Maize ProductionBiostimulants are becoming popular in the agricultural market as products to increase growth, health, and/or yield of crop plants. These products differentiate themselves from traditional plant growth regulators as they impact crop growth and development indirectly through mitigation of crop stress and/or greater nutrient availability and uptake. The challenge in working with these products is that there are many types of biostimulants, each with unique mechanisms of action. The objective of this... C.N. Sible, F.E. Below |
4. Banding Nitrogen Increases Nutrient Uptake and Yield of CornInadequate nitrogen (N) availability during the start of the corn (Zea mays L.) growing season can reduce the yield potential of the crop. However, the greatest amount of N is required during the period of rapid growth (from 10-leaf stage to tasseling [VT]). Banding N at or near the time of panting increases availability of N to the corn plant and could allow for the reduction in early-season N rates without reducing yield potential. Across the state of Illinois in 2019, urea ammonium nitrate... E.T. Winans, F.E. Below |
5. Evaluation of Instinct II and Radiate on Soft Red Winter Wheat in Northwest OhioProducers in Northwest Ohio are encouraged to purchase various additives for urea-ammonium nitrate (UAN) with the expectation to increase grain yields; however, they have limited information on the benefits of these products except what was provided by the selling company. Two products that were commonly promoted were Instinct II, a nitrification inhibitor, and Radiate, a growth regulator. A three-year study was completed at the OARDC Northwest Agricultural Research Station near Custar, Ohio to... E.M. Lentz |
